Which of the following statements are correct regarding the transmission of neural signals between nerve cells in the human body?
1) Signals are received in nerve cells through dendrites
2) Signals are sent from a nerve cell to another one through axon
3) Signals can be received and sent in nerve cells through dendrites
4) Signals can be received and sent in nerve cells through axons
5) Axon is wrapped around by layers of myelin produced by the Schwann cell to prevent neural signal strength reduction (or deterioration) during transmission
6) Multiple nerve cells are involved in receiving signals from an affected area of the body, such as a sharp object piercing through our skin, and this information will be forwarded to the brain for decision making, thereby creating a neural network
7) It usually takes many seconds for a signal to be sent from a finger to the brain, such as when a person touches a hot stove since the brain needs the time to make correct analysis, judgment, and decision
